NON-REFILLABLE BOTTLE.

Speccaton of Letters Patent.

Patented Jan. 12, 1915.

Application led July 14, 1913. Serial No. 778,970.

To all whom t may concern.'

Be it known that I, JOHN C. UHLEIN, a citizen of the United States,residing at Watertown, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in non-relillable bottles and the object in view is to produce a simple and eflicient device of this nature so arranged that, in the event of any attempt being made to refill the bottle, whether the same is located in a vertical, inclined or horizontal position, means is provided for causing the valve to seat against passage of any fluid into the bottle.

My invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which y Figure 1 is a central vertical sectional view through the neck of a bottle and valve mechanism contained therein. Fig. 2 is a similar section showing the bottle tilted and the valve automatically seated. Fig. 3 is a detail perspective view of a shell contained within the upper portion of the neck. Fig. 4 is a detail perspective of a member having a recess with conical wall. Fig. 5 is a detail perspective view of the valve, and Fig. 6 is a detail perspective View of the shell containing the valve seat and guide ribs to the valve.

Reference now being had to the details of the drawings by letter, A designates the neck of a bottle, the inner wall of which tapers slightly as at A and B is a shell, the outer surface of which tapers to correspond with the tapering surface of the neck against which it contacts and by which it is supported. Said shell has a central openlng D, the upper marginal edge of which is slightly beveled as at E, forming a valve with a shank portion H', the end of which is conveXed as at N.

A member, designated by letter O which is cylindrical in outline, is provided with ribs O projecting from the circumference thereof,y the lower ends O2 of which project below the lower end of said member and are adapted to rest upon the flat top K of the shell B, allowing a slight space to intervene between the latter and said member through which liquid may be allowed to flow as it is dispensed from the bottle. The under surface of the member O is chambered and has a conical wall Q which, at its upper end,

, terminates in an aperture R leading through the top of said member and provided for` the purposev of preventing any vacuum which might otherwise form in the upper portion of the chamber Q and which would have a tendency to hold the valve from moving to its seat to prevent the refilling of the bottle.

'A double shell T, provided with passageway T between the same and with its lower end T2 flaring, is inserted within the neck with the inner flaring end resting upon the upper ends of the ribs O upon the member O, thus providing means for allowing the liquid to pass through intermediate the inner flaring end and the member O to allow liquid to flow from the bottle. The bottom T3 of the inner shell portion, as shown in Fig. 2 of the drawings, is closed and which will prevent the possibility of a wire being passed therethrough in the event of any attempt` being made to tamper with the valve to hold the same from unseating.

Upon reference to Fig. l of the drawings, the passageways through which liquid may pass out of the bottle, when the valve is unseated, is designated by arrows and in Fig. 2 the valve is shown as having been automatically closed by the tilting of the neck to substantially a horizontal position.

In operation, When it is desired to dispense liquid from the bottle, it may be done by merely tilting the bottle to alloW the valve to fall from its seat, the liquid taking the course designated in Fig. l by arrows. In the event of it being attemptedto refill the bottle While the same is in upright position, the valve would, of course, close by gravity and, in the event of any attempt being made to refill the bottle While turned down toward a horizontal position, it Will be noted that the conveXed end N of the valve stem, being in contact With the sloping surface of the chamber Q', Will slide down said surface and cause the sphericalshaped end of the valve to seat, the valve being guided in its movements by the projections or ribs upon the inner surface of the shell B as Will be readily understood. This action of the valve by gravity is so sensitive and positive that the slightest attempt to turn the bottle to a horizontal position Will cause the valve to quickly slide to its seat, rendering it impossible to pour or force any liquid into the bottle and any attempt to refill the bottle in the event of the latter being inverted Would be naturally prevented by the trapping of air Within the bottle.

What I claim to be new is A non-rellable bottle, a cup tted therein and provided With an opening in its bottom, the inner Wall of said cup flaring near its upper end, a member having a series of circumferential ribs which extend belovv the lower end thereof and resting upon said cup, the under surface of said vmember having a conical-shaped recess formed therein and terminating at its apex in an aperture leading through the member, a valve With a conveXed surface and having a shank portion terminating in aconveXed end adapted to have a sliding contact With the conical Wall of said recess as the bottle, after having been inverted to dispense liquid, is turned toward a horizontal position to cause the valve to move by gravity to its seat, as set forth.

In te'stimony'vvhereof I hereunto ailiX my signature in the presence of tWo Witnesses.
